I am so sorry to hear about poor Colby. It breaks my heart. I don't understand why the original vet lied about the labs and why your vet didn't notice the abnormal results and I wonder what the breeder has to say about that...I know he is at peace now, but I know you and your family have huge holes ripped in your hearts and there is nothing that I can do or say except I am crying for your loss. RIP little Cole Bear.
